I-Polymetry |

kusukela ku-Greek polus - abaningi kanye ne-metron - isilinganiso

Ukuxhumana kwamamitha amabili noma amathathu ngesikhathi esifanayo, enye yezindlela ezivame kakhulu zenhlangano ye-polyrhythm.

I-P. ibonakala ngokungafani kwemethrikhi. ama-accents ngamavoti ahlukene. U-P. angakha amazwi, lapho ubukhulu bungaguquki noma buguquguqukayo, futhi ukuhlukahluka akubonisi ngaso sonke isikhathi kumanothi ezincwadi. izimpawu zedijithali.

Isisho esimangalisa kakhulu se-P. siyinhlanganisela yokubola. amamitha kulo lonke i-Op. noma ingxenye enkulu yayo. U-P. onjalo uhlangana kancane; isibonelo esaziwayo inkundla yebhola evela ku-Mozart's Don Giovanni ne-counterpoint yemidanso emithathu kumasiginesha wesikhathi esingu-3/4, 2/4, 3/8.

I-polymetric emfushane evamile evamile. iziqephu ezenzeka ngezikhathi ezingazinzile ze-classic. amafomu, ikakhulukazi ngaphambi kwama-cadences; njengama-elementi egeyimu, kwezinye izimo asetshenziswa ku-scherzo, lapho akhiwa khona kakhulu ngesisekelo sobukhulu be-hemiola (bona isibonelo esivela engxenyeni yesi-2 ye-quartet yesi-2 ye-AP Borodin).

Uhlobo olukhethekile yi-motivic P., esinye sezisekelo zokwakheka kwe-IF Stravinsky. P. e-Stravinsky ngokuvamile inezingqimba ezimbili noma ezintathu, futhi ngayinye yazo ichazwe ubude nokwakheka kwesisusa. Ezimweni ezijwayelekile, elinye lamazwi (i-bass) li-ostinaten ngokuzwakalayo, ubude besisusa kulo abuguquki, kanti kwamanye amazwi liyashintsha; umugqa webha ngokuvamile usethelwe ukuthi ufane kuwo wonke amazwi (bona isibonelo esivela endaweni yokuqala ye "Indaba Yesosha" ka-IF Stravinsky).
